“…The topology of phylogenetic tree obtained in this study is largely consistent with previous phylogenetic study of Elaeagnaceae based on ITS sequences of nuclear rDNA, which showed that Elaeagnus glabra was clustered with Elaeagnus macrophylla , while Elaeagnus multiflora was clustered with Elaeagnus umbellate (Son et al. 2014 ). In the future, more species and more samples from each species are necessary to fully resolve the phylogeny of Elaeagnaceae.…”

Elaeagnus pungens is an evergreen shrub with high medicinal values. In this study, the complete chloroplast (cp) genome of E. pungens was characterized. The chloroplast genome of E. pungens is 152,218 bp in length, consisting of two 25,876 bp inverted repeats, 18,231 bp small single copy region, and 82,235 bp large single copy region. The chloroplast genome contains 113 unique genes, including 79 protein-coding genes, 30 tRNA genes, and 4 rRNA genes. Phylogenomic analysis revealed that E. pungens and species from Elaeagnus formed a monophyletic clade sister to the clade consisting of species from Hippophae .

“…Currently, several phylogenetic studies have provided credible insights for understanding the evolutionary relationships of Elaeagnus , and the consensus trees supported the monophyletic origin of the genus Elaeagnus and Hippophae ( Bartish et al, 2002 ; Kim et al, 2020 ; Zhao et al, 2020 ). Son et al (2014) provided the molecular phylogenetic relationships of nine common Asian Elaeagnus species based on nrDNA ITS sequences. Their study reported that different clustering methods can be used for obtaining similar divergent results, except for the ambiguity in the divergence time of the outer taxa in the genera Shepherdia and Hippophae.…”

Phylogenetic Analysis of Elaeagnus L. in China: A Basis for Genetic Improvement of a Berry Crop

et al. 2022

Elaeagnus L. is found in wild or grown as ornamental plants and is increasingly regarded as underutilized berry shrubs by breeders. This genus has cosmopolitan distribution with various species widely distributed in China, Europe, the United States, and Canada. Interspecific hybrids, which have been reported several times, have attracted intense interest from plant breeders attempting to develop a fruit crop of Elaeagnus. Orthogonal projections to latent structures discriminant analysis (OPLS-DA) is a powerful statistical modeling tool that provides insights into separations between experimental groups. In this study, the molecular phylogeny of Elaeagnus species was first discussed using the ITS and matK sequences for guiding the construction of a genetic basis pool. A morphological OPLS-DA clustering model based on the genetic divergence was also constructed for the first time, which effectively realized the morphological grouping of Chinese Elaeagnus species. The results showed that a total of 10 wild species widely distributed in China have the potential to develop fruit crops. Particularly, Elaeagnus conferta has the potential to provide a founder species with a large fruit size, while Elaeagnus Gonyanthes has the potential to provide important genetic resources with long pedicel. Elaeagnus lanceolata and Elaeagnus delavayi could be used to domesticate hybrids without spines, and the other five climbing shrubs could be used to develop high-yield crown-type commercial cultivars for automated field management. The top five contributing morphological traits affecting the current clustering model were V9 (flower color), V1 (flowering), V5 (evergreen or deciduous), V3 (leaf size), and V2 (fruiting). Furthermore, the grouping analysis indicated that the V9 was the most important factor affecting morphological clustering. Thereafter, the temporally calibrated phylogeny inferred from the matK sequence was used to reconstruct the origin and evolution of the genus Elaeagnus, and the results inferred an interesting geographic distribution pattern and potential cross-species interactions of Elaeagnus species at low latitudes in China. Our study also highlighted dispersal pattern investigation and genetic background analysis to improve future practices and policies related to species introduction of genetic basis pool.

“…chloroplast genomes, has been recently sequenced [5][6][7]. Furthermore, several attempts have been made to identify species in the Elaeagnus by using DNA barcoding when determining phylogenetic relationships and describing new species [8][9][10][11]. In addition, different types of molecular markers have been developed to study genetic diversity in Elaeagnus populations [12][13][14][15][16].…”

The Elaeagnus L. species are trees and bushes that mainly grow in temperate zones of Western Europe; Minor, Central, and Southeast Asia; the Far East; and North America. Some species are used as fruit or ornamental plants and have economic value. Problems with the identification of species in the Elaeagnus genus by molecular genetical methods arise in the study of populations, systematics, breeding, and other areas of plant science and practice. Recently, the polymorphism of 5S ribosomal DNA non-transcribed spacers (5S rDNA NTSs) in Elaeagnaceae Adans. has been described. The results were used in our study as a basis for development of new species-specific molecular markers for some members of the Elaeagnus genus. The author’s method was applied for finding regions that were potentially applicable for species-specific primer design. As a result, some species-specific molecular markers were developed for Elaeagnus angustifolia L., E. commutata Bernh., E. pungens Thunb., and E. multiflora Thunb. These markers were tested in a range of samples and showed the presence of amplified fragments in lanes of the marked species only. Samples of other species showed no amplifications. Thus, the developed markers may be useful for the species identification of the studied Elaeagnus plants in botanical, dendrological, and genetic research (especially in a leafless period of year), as well as in breeding and hybridization experiments.
